ReadOnlyActionEventHandlerPropertyWrapper
class ReadOnlyActionEventHandlerPropertyWrapper(wraps: ActionEventHandlerProperty) : ReadOnlyPropertyWrapper<ActionEventHandler, Property<ActionEventHandler>> , ReadOnlyActionEventHandlerProperty
Never use this class directly. Use ActionEventHandlerProperty.asReadOnly to obtain a read-only version of a mutable ActionEventHandlerProperty.
Boilerplate which avoids having to use generic. Instead of ReadOnlyPropertyWrapper<ActionEventHandler, Property<ActionEventHandler>>, use ReadOnlyActionEventHandlerPropertyWrapper.
